@screwtape @mdhughes @amoroso @michaelc That is really awesome! I am following the updates, but haven't digged into it.
I started something similar, but had performance issues and used claw-raylib and cl-fast-ecs for rendering. Wanted the "editor" part to be in #mcclim though. Probably yet another project I'll never pick up again ;) https://git.sr.ht/~simendsjo/sijo-ion/tree/dev/item/src
It's outdated too, but I recently packaged claw-raylib and cl-fast-ecs for #guix to maybe pick it up (if ever): https://git.sr.ht/~simendsjo/dotfiles/tree/main/item/sijo/packages/gamedev.scm
